Tirukkural 421: Fortress of Wisdom

Wisdom is a weapon to ward off destruction; it is an inner fortress which enemies cannot destroy.

Image of Satguru Sivaya Subramuniyaswami
There is in much of the world the belief that life is a burden, a feeling of penitence, that it is good to suffer, good for the soul. In fact, spiritual life is not that way at all.
—Gurudeva
